Arectangular playground is enclosed by 440 feet of fencing. if the length of the playground is 20 feet less than 3 times the width, find the dimensions of the playground

9600,2(len+wid)=440,len=3*wid-20,len=160,wid=60.

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|

.95
